Please check if nano-graphrag is correctly installed https://github.com/gusye1234/nano-graphrag/

[gutama]

nano-graphrag is running fine under lightrag

I was using docker full installation

docker run -e GRADIO_SERVER_NAME=0.0.0.0 -e GRADIO_SERVER_PORT=7860 -e USE_NANO_GRAPHRAG=true -p 7860:7860 -it --rm ghcr.io/cinnamon/kotaemon:main-full

@gutama currently Docker full installation haven't has nano-graphrag dependency installed yet. We are making some tweaks to nano-graphrag to make it more stable & easy to use before release it as official Docker image.

thank you for the explanation
